I think I just love the name…”INDOW WINDOW”. A friend of mine who works in Portland, OR, posted about these thermal window inserts as promoted by Clean Energy Works Oregon, a non-profit program established to reduce energy waste by encouraging homeowners to take direct action. I contacted the manufacturer to find out if their windows were available in the Seattle area and they are as of the last month or so. Here is the link to the product Indow Windows and the local company that represents them in the Seattle area EcoFab.
